My guy's a bit more mundane than the rest, but I think we need a foil.

Name: David Jones
Age: He's kinda lost track, 30 maybe?
Appearance: On top of the usual helmet-gas mask combo, David has a radio headset with a microphone and earpiece, with a cord running to the large radio box on his back
Rank: Not very many kills, but he's the one with the radio, so he gives the orders from command, and people just kinda do them. He doesn't let anyone else use the radio for this reason.
Position: Radio Operator
Weapons: Semi-Automatic Rifle, a grenade or two, utility knife.
